Last Year

 When I was young, I was taught that last year was said as gu7niⁿ5.

 When I had my Teochew language lessons, my teacher said people in Swatow would say last year as zioⁿ6ni5.

gu7ni5	舊年｜旧年	last year
zion6ni5	上年	last year

 What is strange is two days ago is said as zoiⁿ5rig8 and Mogher has listed zioⁿ6rig8 means two days ago.  Do notice that zioⁿ6rig8 means two days ago where as zioⁿ6ni5 means last year. 

zoin5rig8	前日	two days ago
zion6rig8	上日	two days ago

 How do you say last year and two days ago in Teochew?
